Check Digit Verification of cas no

The CAS Registry Mumber 115377-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,3,7 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 115377-87:
(8*1)+(7*1)+(6*5)+(5*3)+(4*7)+(3*7)+(2*8)+(1*7)=132
132 % 10 = 2
So 115377-87-2 is a valid CAS Registry Number.

Rhodium-catalyzed addition of arylboronic acids to N-sulfonyl aldimines

Ueda,Saito,Miyaura

, p. 1637 - 1639 (2007/10/03)

The addition of arylboronic acids, ArB(OH)2, to N-phenylsulfonyl aldimines, RCH=NSO2Ph (R = alkyl, aryl, 1-alkenyl), giving R(Ar)CHNHSO2Ph was carried out at 95 °C in the presence of a rhodium catalyst. [Rh(cod)(MeCN)2]BF4 (3 mol%) was found to be the best catalyst for aryl aldimines and Rh(acac)(coe)2/i-Pr3P for alkyl and 1-alkenyl aldimines. The analogous reactions of arylboronic esters, such as 1,2-ethanediol and 1,3-propanediol ester, yielded the addition products in the presence of two equivalents of Et3N.
